The aura of a Nascent Soul Realm Expert was way weaker compared to the sword qi that had appeared earlier, but even then, it shocked all of the cultivators present.
Xuan Hao was already in the Nascent Soul Realm before his enlightenment, so him being stronger than someone who had just reached the Nascent Soul Realm was expected.
What shocked them was the fact that someone actually managed to breakthrough to the Nascent Soul Realm! This had only happened one time before and that person had already reached the middle stages of the Nascent Soul Realm by now!
For another Nascent Soul Realm Expert to appear on the Third Star Peak, there would surely be a swarm of new people coming to try their luck on top of the Third Star Peak, like what had happened in the past when the now elder of the Seven Fates Sect reached the Nascent Soul Realm.
